Abstract
An object of the present invention is to provide a welding system wherein the positional accuracy of welding and the quality of welding are improved. The present welding system includes an ultrasonic welder for welding a plurality of webs W together while carrying the webs W. The ultrasonic welder includes: an anvil roller 10 including a pair of anvils 11, 12; a first ultrasonic horn 21 and a second ultrasonic horn 22 that apply vibration energy to the webs W in cooperation with the pair of anvils 11, 12. The pair of anvils 11, 12 are provided symmetrically with each other with respect to an axis line O of the anvils roller 10. The first and second ultrasonic horns 21, 22 apply the vibration energy to the webs W simultaneously while each of the anvils 11, 12 faces the first or second ultrasonic horn 21, 22.
Claims12
A welding system with an ultrasonic welder for welding a plurality of webs together while carrying the webs, wherein the ultrasonic welder comprises:
- an anvil roller including a pair of anvils;
- a first ultrasonic horn and a second ultrasonic horn that apply vibration energy to the webs in cooperation with the pair of anvils;
- and
- carrying means for carrying the webs so that the webs pass a first gap between the anvil roller and the first ultrasonic horn and then pass a second gap between the anvil roller and the second ultrasonic horn,
- the first and second ultrasonic horns are arranged so that one anvil of the pair can face the first ultrasonic horn at the same time as the other anvil of the pair faces the second ultrasonic horn, and
- the first and second ultrasonic horns apply the vibration energy to the webs simultaneously while each of the anvils faces the first or second ultrasonic horn,
- wherein the pair of anvils are provided symmetrically with each other with respect to an axis line of the anvil roller.
